Father of two Steve Baker signed a contract with Huxley Homes, a subsidiary of Home Australia Group in New South Wales, in 2014 for what was supposed to be a nine-month build.
It's still a construction site, and his family is unable to live in it - with no power, water or plumbing connected.
"So at the moment we're just looking at our options, what can we do, we're sitting here with a builder who's telling us that they can't build our home. So we're just looking at what options we have available to us. All we really want to do is get into our home."
He's not alone.
For months SBS News has investigated similar stories involving Huxley Homes and four other building companies across the country, owned by South Australian Family First Senator Bob Day.
Elizabeth Scuteri put a $26,000 deposit on her home and two years on is yet to see it built.
"I just started balling my eyes out because that's my family dream, we're heartbroken. We have no money to build this house. We have no money to pay our trades. We're not even paying rent. We don't even know what's going to happen."
Senator Day has told employees that with great sadness his parent company Home Australia has gone into liquidation.
In a statement he says, he intends to "pay back every debt fully, no matter how long it takes."
He adds that he is "incredibly sorry for the pain, stress and suffering he knows it will cause".
For most customers, this will likely come as a relief because insolvency is a trigger for them to be covered by home warranty insurance.
But tradesmen and other sub-contractors will have to get in line with other creditors.
Independent Senator Nick Xenophon says the collapse highlights the urgent need for changes to security of payments legislation.
"Our security of payments laws for subcontractors in this country is a complete mess. It's an ad hoc approach, it is inconsistent state by state and it doesn't give protection to those subcontractors, to the concreters, carpenters, tilers, the plumbers the electricians who've actually put their own labour, the labour of their employees they've paid for and putting in their own materials for these projects."
Bob Day has been the Coalition government's strongest crossbench ally, and supports the two union-related bills used to trigger the double dissolution election.
Former Prime Minister Tony Abbott was among those paying tribute, saying Senator Day has taken the honourable course and that he hasn't sought to avoid responsibility or blame anyone else.
But Bob Day appears to have tried to shift some blame to a Philippines-based company, which he claims was set to buy a big stake in Home Australia, but the money apparently never arrived and was based on fraudulent documentation.
After 40 years in the business he started, Senator Day says he looks to lose his family home.
The South Australian Family First party will nominate a replacement to fill the vacancy.
